Description

The air-conditioning of lathe
Technical field
The present invention relates to machine tool field, relate to particularly the improvement project that air conditioning is remained on to optimum state.
Background technology
The cooling of lathe is a kind of function of some lathe, and it is for monitoring as far as possible, change and/or keep the different piece thermal environment of living in of lathe, to guarantee the precision of process operation.In fact, the source that expansion relative to each other of member or contraction can become error.When the structure of lathe comprises that thereby the parts of being manufactured by different materials have the different coefficients of expansion, these shortcomings become and are difficult to control when there is no air-conditioning.
Existing cooling scheme is included in and forms box structure in structure, on it, with entry and exit, from the cooling fluid of a Climate Control Module in lathe, flows through this entry and exit.These solutions are for various machine tool structures.
In addition, without cooling agent or only have the latest developments of the high speed machining (be called MQL processing) of a small amount of liquid, caused near temperature processing station to rise and the maintenance of this temperature.Although it is known that the air conditioner support of lathe is provided, to the air-conditioning of the sub-component of supporting workpiece, be rare.Therefore, though to air-conditioning need to be known, the solution of all correlation function modules of lathe is not but existed, and/or the implementation cost of such solution makes this solution become unrealistic.
Summary of the invention
Based on above-mentioned situation, the inventor is studied, to provide a kind of tool air-conditioned machining tool, thereby provide a kind of simple and with low cost cooling solution, this solution can cover the functional module that frame and work support with lathe are connected.
Lathe according to the present invention comprises a framework for tool motion and a work support, it is characterized in that, it comprises a plurality of heat exchangers, and heat transfer fluids flows through these heat exchangers, and described heat exchanger communicates with each other and contacts with described frame and work support.
The advantageous particularly part of this feature is, it provides a kind of air-conditioning and lathe temperature to control solution, and this solution especially flexibly and be convenient to implement.Be formed on a plurality of heat exchange zones on the wall of lathe, in the surrounding of this wall, produced hot isolation.
Further, all heat exchangers only need a single refrigerating module.In addition, this solution makes the form of heat exchanger have large flexibility, thus can with the dissimilar fit that need to carry out the wall of refrigeration/air-conditioning.These heat exchangers can be installed to any part of lathe, or any part or the equipment that are connected with the machine tool frame that need to obtain air-conditioning.Therefore, for example, switch cubicle and fluid also can be equipped with described heat exchanger.In addition, this lathe can comprise the holder part being connected with its frame or hold a work support that is fixed to described frame.
For this flexibility of facility and make it possible to design heat exchanger array, described lathe comprises a plurality of independent heat exchangers, and these heat exchangers are connected by flexible duct.Therefore, for example, when work support is connected with described frame, one or more heat exchanger of work support is connected with the heat exchanger in described frame.
According to another particularly advantageous characteristics of the present invention, each heat exchanger comprises one group of pipe, and it has the form of coil pipe and is arranged on prefabricated insulation panel, and this insulation panel is connected to the wall of frame or work support.Therefore, each panel forms the individual components being connected with other panel by flexible pipe.Configuration makes the manufacture of aircondition can not rely on the frame that this configuration adopts like this, and the lathe that can either provide aircondition also can provide the lathe that there is no aircondition.Having so the independently configuration of panel can be used in existing lathe is carried out to air-conditioning.
According to another feature, each heat exchanger has a hollow body, this hollow body with the entrance flowing through for heat transfer fluids and or outlet, this entrance and exit makes this heat exchanger be connected with other heat exchangers.According to one embodiment of present invention, this hollow body can form railway carriage or compartment, and a part of wall in this railway carriage or compartment consists of the wall of described lathe.
According to a particularly advantageous characteristics of the present invention, at least one heat exchanger is arranged on the frame below of lathe, and according to a further feature, at least one heat exchanger is arranged under described work support module, thus advantageously utilize with the flat that to want cooling region nearest.
According to another feature, described lathe comprises a reversible air-conditioning unit.This invertibity makes described lathe can under cold or hot severe temperature environment, work and guarantee the precision of processed parts.
According to another feature, described lathe comprises that a capable of regulating power is the air-conditioning unit of variable output.This adjusting makes the temperature in heat exchanger at any time can be controlled, thereby can control the geometry of this lathe.The temperature that flows through the heat transfer fluids of described heat exchanger obtains very meticulous control.According to an embodiment, described air-conditioning unit comprises an engine, and this engine is provided with the heat transfer fluids that temperature fluctuation is reduced.
According to another feature, described air-conditioning unit is used to the temperature of the air in controlled working chamber.The air being inhaled in this chamber first passed through a heat exchanger before entering machining area.
Above basic conception of the present invention is described.From below in conjunction with the description of the drawings, and by not determinate embodiment, the embodiment according to lathe of the present invention is described.
Accompanying drawing explanation

Fig. 2 is the stereogram of bottom view of the lathe in Fig. 1.
Fig. 3 is the view that only has air-conditioning panel that the visual angle identical with Fig. 1 seen.
Figure 4 and 5 are top view and stereograms of the panel of an embodiment.
The specific embodiment
As illustrated in fig. 1 and 2, the lathe of enerally designated M comprises a plurality of functional modules, comprising:
-mono-motion module P1, it comprises a frame 100, in this frame 100, is provided with the actuating structure for the motion of cutter, and is fixed with a control module M in this frame 100;
-mono-processing station P2, it comprises a work support 200 and is positioned at the place ahead of motion module P1;
-mono-supply station P3 supports for the device of the electric power of other functional modules is provided.
According to object of the present invention, for being provided, the optimum temperature of lathe M controls, a plurality of heat exchangers are installed on the wall of frame 100 and work support 200, and these heat exchangers are implemented with the form of interconnective panel 300, and have formed one group of panel of the whole demonstration of institute in Fig. 3.
